MOTORS CORPORATION, OF DETROIT, MICHIGAN, A CORPORATION OF VIRGINIASLEEVE VALVE E GINE CYLINDER HEAD Application filed November 16, 1927.SerialNo. 233,550.

This invention relates to internal combustion engines and-refers moreparticularly to the sleeve valve type of engine. In this type of enginethe upper extremity of the sleeve ordinarily works in a pocket formedbetween the cylinder head and cylinder. While the cylinder head isordinarily jack-' eted for cooling water, the amount of availablejacketing is limited dueto sparkplug m location and general arrangementof parts.

As a result thesleeve jacket tends tobecome overheated resulting information of steam pockets, carbon accumulation and general in efiicientoperation of the engine.

in providing means for overcoming the above objectionablecharacteristics; To-this' a positive circulation of cooling water forcooling the cylinder head; sleeve pocket, and spark plug. I

I have provided a'member preferably in the nature of a simple sheetmetal stamping associatedwith' the cylinder head for of parts moreparticularlyhereinafter described and claimed.

Referring to the accompanying drawings in which like referencecharacters represent corresponding parts,

In the drawings reference character 10 represents one or more enginecylinders with associated pistonll and sleeve valve 12,.the latter forillustration being shown asthe Burt-M cOollum single sleeve valve typein which the sleeve is moved, in a combined reciprocating andoscillating path with respect to the sleeve axis in moving the-sleeveports 13 to function With' the cylinder ports 14; 7 j

Thecylinder is closed at the top by a cylinder head 15 which may beformed With walls 16 and 17. The wall-16 together with the associatedcylinder forms a valve pocket 17 accommodating the movement of the upperportion of the sleeve valve 12. The wall 17 is spaced from thewall 16 toform the cylinder head cooling water jacket 18 and also defines thecombustion chamber. 19. The wall 17 may be extended to provide a barrel20 with the spark plug opening 21. The cylinder head 15 may be securedto the cylinder by studs 22 at the corners of the cylinder head flange23.

The cooling Water from jacket 24 is open for communication with thecylinder head jacket 18' through opening '25 preferably mainly'along oneside only of the cylinder head. For guiding the water from o ening 25 Ihave provided a member 26 pre erably formed of a sheet metal. stamping;The member 26 may be formed with wall 27 spaced from the side of thecylinder head adjacent the opening 25, side walls 28, and

top wall '29. The water in moving across I ARCHIE MAorHAIL- NIVEEN, orDETROIT, MICHIGAN, ASSIGNOR T0 CONTINENTAL with the cylinder head andwhich divide the jacket 18 longitudinally. Cooperating with baffles 30are bafiles 31 preferably formed integrally with the main body of themember 26. The top wall 29 is formed with a semi-circular or recessedportion 82 preferably open at an edge of said member and engageable withthe barrel 20 preferably below the sealing structure or ring 33. A nut34 threadedly engages barrel 20 for clamping the cylinder head cover 35and sealing ring 83 in position as shown in the drawings. One feature ofmy invention resides in the manner in which the barrel conveniently 10-cates the member 26 in its proper position,

at the same time permitting removal of this member (after removing nut34L and cover 35) independently of the sealing ring 33. This is quiteimportant since the sealing ring 33 after use becomes worn in affordinga tight sealing joint, it being desirable not to disturb this joint inremoving the cylinder head. In order to further prevent displacement ofthe member 26 as might occur from the water fiow, I may provide a lug 36projecting inwardly from cover 35 and either engaging the member 26 orin proximity thereto. If desired the projection or lug might be formedwith the member 26 and engageable with the cover 35 as will be readilyunderstood.

The cooling water may be circulated throughout the entire system by theusual water pump (not shown), the water being returned to the usualradiator by a header 37 on the outlet side of baffles 30, 31.

My invention is equally well adapted for use with various types ofsleeve valve engines such as multiple or single sleeves having variousmovements.
